we are using a cluster of exchange 2010.
Now each user has an own email address like: email@example.com
We want to change this in the future for each user. Lets say each user is also reachable by another email like: firstname.lastname@example.org
I know I can create a new email for each user and add it to his account.
But when we want to use the new structure with email@example.com , is there a quick way to change it ?
